Delete node

[AmazingRando]

I got the search problem figured out, and now am applying the same idea to a delete node function
but the function fails to return to the main menu after it is done

//Node structure
typedef struct node_d
{
char city[40];
char state[3];
char zipcode[6];
double longitude;//double
double latitude;//double
long population;//long
struct node_d *previous;
struct node_d *next;
}Node;

//Header structure
typedef struct
{
struct node_d *psHead;//might change this to node_d
struct node_d *psTail;
struct node_d *psCurrent;
int node_count;
}Header;

int Delete_Data(Header *psList,Node *list,Node *node, int z)
{
	int x, n = 1, indicator = 1; 
	char answer[40], delete_[1], confirmation[1];
	strcpy(confirmation,"y");
	node = psList->psHead;
	printf("\n\nWhat City or Zipcode would you like to delete?");
	scanf("%s",&answer);
	
		if (isdigit(answer[0]) != 0)
		{
			//search for zip
			for(x=0;x<z;x++)
			{
				if( strncmp( answer,(node->zipcode), 6) == 0 )
				{
				
				system("cls");
				printf("\nZipcode = %s   City = %s   State = %s",node->zipcode, node->city,node->state);
				printf("\nPopulation = %d  Longitude = %-.2f  latitude = %-.2f\n",node->population,node->longitude, node->latitude);
				indicator = 0;
				printf("\nAre you sure you want to delete this record?");
				printf("\npress 'y' for yes and 'n' for no\n");
				scanf("%s",&delete_);
				if(strcmp(delete_, confirmation) == 0)
				{
					node->next->previous = node->previous;
					node->previous->next = node->next;
					free(node);
					printf("node deleted");
					n = 0;
				}
				
				}
			node = node->next;

			}
			if(indicator !=0)
			{
				printf("\nRecord not found\n\n");
			}

		}
		else 
		{
		//search for city
		for(x=0;x<z;x++)
		{
			if( strncmp( answer,(node->city), 6) == 0)
			{
				
				system("cls");
				printf("\nZipcode = %s   City = %s   State = %s",node->zipcode, node->city,node->state);
				printf("\nPopulation = %d  Longitude = %-.2f  latitude = %-.2f\n",node->population,node->longitude, node->latitude);
				indicator = 0;
				printf("\nAre you sure you want to delete this record?");
				printf("\npress 'y' for yes and 'n' for no\n");
				scanf("%s",&delete_);
				if(strcmp(delete_, confirmation) == 0)
				{
					node->next->previous = node->previous;
					node->previous->next = node->next;
					//free(node);
					printf("node deleted");
					
				}
				
			}
			node = node->next;

		}
		if(indicator !=0)
		{
			printf("\nRecord not found\n\n");
		}
		}//end else

return 0;
}

You guys have any ideas on why it does this?
The last thing I get is the printed message "node deleted"
and then crash

You are leaving no room for the string terminator. delete_ and confirmation should be at least two chars:
char answer[40], delete_[2], confirmation[2];

Or alternately you could make them a single char:
char delete_, confirmation;
Then use:
scanf("%c",&delete_);
if(delete_ == confirmation)
